Hellooooo devola
Another awesome character, you are like a well of ideas! If I may, I have some suggestions on the anatomy, but before I go into details, I want to say how impressed I am by the improvement you've shown in just a few weeks!!! It is refreshing to see an artist who sets aside his ego, takes in any kind of advice or help , even the smallest hints, and focusses on improving in a modest manner like yours. I draw my hat, and when you hit any point in your project where you need help, please feel free to ask me!
At first, I just felt something is off with the ellbow and I am not quite sure if I fixed it tbh. But maybe the issue is because of the staff - the more you strech out the arm, the more difficult it seems to stay behind the staff. The hand could probarbly drawn more from the side than I did to better show where the arm is supposed to be - to the back.
Now, if you strech up your arm, the breast on that side is pulled upwards and flattened a bit - with just a small adjustment, you'll gain even more tension to the already good pose.
You like to draw poses with one leg lifted, and often that liftet thigh is a bit too short and also thinner than the other. Judging from the perspective, I'd say there is no shortening, so maybe just have the courage to draw it a bit bigger anyway, even if it feels too long at first. It's your style to draw long legs, and in some poses it can look exaggerated on the first glance, but I am positive it will balance out with the whole figure :)
I am so looking forward to see the finished products of your last posted sketches, keep up the good work, keep improving! People like you are gems amongst rocks.
